Project abstract

marGnet will set up and test multi-level solutions to monitor, map, prevent, remove and recycle marine litter from sea-based sources present on the seafloor.

The 'marGnet' project is promoted by a consolidated Consortium, led by CNR-ISMAR, that have successfully cooperated in past projects and initiatives, such as the GHOST project. It integrates scientific and technical public and private bodies (CNR-ISMAR, Laguna Project s.n.c., Techneprojects s.r.l.s), an innovative start up SME (Sintol s.r.l.) and NGO (Blue World Institute of Marine Research and Conservation). The 'marGnet' project focuses on marine litter (ML) from sea-based sources, precisely to the ML on the sea floor and especially on ML generated by the fisheries and aquaculture activities, including not only abandoned, accidentally lost and otherwise discarded fishing gears (ALDFG), but also all the litter that generate by the on-board fish and ichthyic products management, such as Styrofoam boxes and other general waste produced during aquaculture activities as well as the ordinary waste generated by the fisheries activities (exhausted nets and their components). In this scenario, it sets up and tests multi-level solutions oriented to, on one hand, monitor and map and, on the other hand, prevent as well as remove and recycle ML from sea-based sources. It provides for:

  1. fast methodology (ba sed on large scale acoustic remote sensing) for wide scale mapping and monitoring of diffusion of marine litter on the sea floor (WP3 and WP5);
  2. a prototype that exploits low temperature pyrolysis method to transform the marine litter in an energy source with reasonable costs (WP4);
  3. policy makers and institutions decision supporting tools and best experience to orient the policy making process (WP5).

It acts on two pilot sites of North Adriatic sea (in IT and HR), ensuring nevertheless a strong replicability due to the they offer the possibility to test the approaches and the methods provided by the project (with specific reference to fast methodology based on large scale acoustic remote sensing) in very different habitats (sandy seabed, rocky outcrops, rocky seafloor) that are representative of the majority of the sea floor types of the European Seas. 'marGnet' is also relevant for its strong contribution to main EU policies and legislation in matter of marine protection and ML management, waste and circular economy as well as integrated maritime policy and port facility management. Indeed, adopting a multilevel approach, 'marGnet' tackles the ML phenomenon from different point of view providing solutions that could be (and the project support for) mainstreamed and up-taken at policy level.

Lastly, the 'marGnet' project provides for pilot development of solutions with high demonstrative features exploiting the state of the art technologies such as low temperature pyrolysis, bringing it to operational scale, overcoming therefore the laboratory stage.
